Flashcard 1
Q: What is a rock?
A: Rocks are a naturally occurring collection made up of two or more minerals.
Flashcard 2
Q: What is a mineral?
A: A naturally occurring solid substance with its own chemical composition, structure, and properties.
Flashcard 3
Q: What is a crystal?
A: A small, organized particle in rocks, with smooth sides and sharp edges.
Flashcard 4
Q: What is an ore?
A: A rock containing a large amount of useful mineral.
Flashcard 5
Q: What properties and composition can be used to identify different minerals?
A: Minerals can be identified by their properties and composition, though specific details vary.
Flashcard 6
Q: What should you do to investigate and compare the properties of different minerals?
A: Perform tests that measure physical and chemical properties to compare minerals.
Flashcard 7
Q: How do you identify common rock types?
A: Use a key based on observable physical and chemical properties.
Flashcard 8
Q: What tests are used to identify minerals?
A: Tests include Lustre, Streak, Cleavage, and Hardness.
Flashcard 9
Q: What are examples of igneous rocks?
A: Basalt, Pumice, Granite, and Obsidian.
Flashcard 10
Q: How are intrusive and extrusive igneous rocks formed?
A: Intrusive rocks form inside the Earth slowly, while extrusive rocks form on the surface quickly.
Flashcard 11
Q: Where are igneous rocks used in everyday life?
A: Igneous rocks are often used in construction and for decorative stone.
Flashcard 12
Q: What properties of igneous rock make them suitable for everyday use?
A: They are durable and often have a high compressive strength.
Flashcard 13
Q: What are examples of sedimentary rocks?
A: Conglomerate, Shale (mudstone), Sandstone, and Limestone.
Flashcard 14
Q: How are chemical, clastic, and biological sedimentary rocks formed?
A: They form through compaction and sedimentation over time, with different processes for each type.
Flashcard 15
Q: Where are sedimentary rocks used in everyday life?
A: Sedimentary rocks are used in construction, cement, and building materials.
Flashcard 16
Q: What properties make sedimentary rocks suitable for everyday use?
A: They are often easy to work with and readily available.
Flashcard 17
Q: What is the difference between controlled, dependent, and independent variables?
A: Controlled variables are kept constant, dependent variables are measured, and independent variables are changed in an experiment.
Flashcard 18
Q: What is important about recording and managing data?
A: Data should be accurately recorded and organized to ensure reliable results.
Flashcard 19
Q: How do you choose the appropriate graph for data?
A: Select a graph type based on the nature of the data and what you aim to illustrate.
Flashcard 20
Q: How can claims be evaluated in science?
A: By analyzing claims based on scientific evidence.
Flashcard 21
Q: How is data used to describe trends and draw conclusions?
A: Data can show patterns or trends that support or refute hypotheses.
Flashcard 22
Q: Why is it important to refer to relevant data when drawing conclusions?
A: To ensure that conclusions are based on evidence and are accurate.
Flashcard 23
Q: How can scientific knowledge be related to investigation outcomes?
A: By applying theoretical knowledge to explain observed results.
Flashcard 24
Q: Why use relevant key terms in expressing ideas and conclusions?
A: Key terms improve clarity and precision in scientific communication.
